Problems solved by technology

[0002] When the slot in the middle of the scraper machine is in harsh working conditions, it will cause deformation of the scraper machine. During maintenance, it needs to be corrected. The existing method uses a 1,000-ton press for calibration. One person operates the equipment, and two To fix the middle groove manually requires the assistance of barley driving operators. Using the existing method for calibration is time-consuming and laborious, and the operation is inconvenient. Only 20-25 knots can be corrected a day. The calibration efficiency is low and the labor intensity is high. It is easy to cause uneven defects in the middle groove and damage to the operator, and poor calibration safety

Embodiment 1

[0028] Embodiment 1: as Figure 1-2 As shown, a device for correcting the middle groove of a scraper machine includes a two-way hydraulic cylinder 1, the end of the cylinder rod 4 of the hydraulic cylinder 1 is connected to the support 2 through a rotating pin 12, and the support 2 is movably placed in the middle groove 3 and limit it left and right. The tail end of the cylinder barrel 5 of the hydraulic cylinder 1 is connected with an inverted U-shaped card slot 6, and the U-shaped card slot 6 is engaged with the pin row pin fixing plate 13 on the upper right side of the middle slot 3. superior.

[0029] The above-mentioned support 2 is provided with a support plate 7 of the cylinder 5, and its lower left side is provided with an abutment plate 9, and the right end of the support plate 7 is placed on the upper end surface of the middle groove 3, and a U-shaped groove 8 inclined downward to the right is arranged under it. , the abutment plate 9 abuts against the left side wal...

Embodiment 2

[0036] Embodiment 2: A method for correcting a device for correcting a slot in the middle of a scraper machine, the method comprising the following steps:

[0037] (1) Install the support in the middle groove, and snap the U-shaped slot of the hydraulic cylinder to the part to be bent on the middle groove pin row pin fixing plate;

[0038] (2) Connect the oil inlet pipe of the hydraulic cylinder to the hydraulic pump;

[0039] (3) Set the oil pressure threshold 10MPa and pressure change rate of the oil inlet pipeline through the controller;

[0040] (4) When the oil pressure reaches 80% of the pressure threshold from 0, the pressure change rate is controlled at 0.5MPa, and between 80% and 100%, the pressure change rate is controlled at 0.25MPa;

[0041] (5) When the pressure threshold in step (4) reaches the maximum, the time lasts for 3-5 minutes, and the oil return of the hydraulic cylinder is loosened, and step (4) is repeated 3-5 times;

[0042] (6) Repeat steps (1)-(5) ...

Abstract

The invention discloses a calibration device of a middle groove of plate scraping machine and a calibration method thereof. The calibration device comprises a two-way hydraulic oil cylinder, wherein the end of a cylinder rod of the hydraulic oil cylinder is connected to a support seat via a rotation pin; the support seat is movably arranged in the middle groove and is limited left and right; the tail end of a cylinder barrel of the hydraulic oil cylinder is connected to an inverted U-shaped clamping groove; the U-shaped clamping groove is clamped to a pin rail pin fixing plate at the upper end of the right side of the middle groove. According to the calibration device, the U-shaped clamping groove is clamped to the pin rail pin fixing plate at the upper end of the right side of the middle groove; the bent part of the pin rail pin fixing plate can be calibrated by extension and shrinkage of the two-way oil cylinder; the calibration device is convenient and rapid in calibration; time and labor are reduced; the calibration efficiency is high; the damage to equipment and the injury to staff can be avoided; the safety is higher; the calibration flatness is higher; the calibration device also has the characteristics of simple structure, low cost and convenient and rapid in operation and maintenance.

Description

technical field [0001] The invention relates to a correction device and a correction method for a slot in the middle of a scraper machine, and belongs to the technical field of scraper machine maintenance devices. Background technique [0002] When the slot in the middle of the scraper machine is in harsh working conditions, it will cause deformation of the scraper machine. During maintenance, it needs to be corrected. The existing method uses a 1,000-ton press for calibration. One person operates the equipment, and two To fix the middle groove manually requires the assistance of barley driving operators. Using the existing method for calibration is time-consuming and laborious, and the operation is inconvenient. Only 20-25 knots can be corrected a day. The calibration efficiency is low and the labor intensity is high. It is easy to cause the unevenness of the middle groove and the operator's injury, and the correction safety is poor. Contents of the invention [0003] Th...
